Incoming traffic from port 443 not working anymore

I'm working on a software demo to show some people and I'm running everything locally for now. Last night it was working great - traffic was coming in on port 443. As of today, my web service (Vercel) is showing a 403 Forbidden error when it tries to access my service via a subdomain -> my public IP. I suspect Comcast is now blocking incoming traffic to port 443 for my public address, but I'm not sure. Can I get some help with this?

Did you ever find a resolution? I think I may be having the same question. Also I saw a related thread here but with no clear resolution: https://forums.xfinity.com/conversations/your-home-network/port-443-blocked/656cdc50cc3f661cfc854b66

I now have port 443 forwarding working. It did not work initially, but the next day it started working. So I am confirming it should be possible to get it to work.
